Subject: [PATCH] acpi: fix section mismatch warning in asus_acpi.o

Fix following section mismatch warning in asus_acpi.o:

WARNING: drivers/acpi/asus_acpi.o(.init.text+0xb7): Section mismatch: reference to .exit.text: (after 'init_module')

The exit function is used in the init function during an error codition.
As __exit may be discarded during link-time / run-time this is no good.
Do not mark the exit function __exit.

Note: This warning is only generated by a local copy of modpost
      but it will soon hit upstream.
